Comments about American Aldes Aldes VentZone Register Terminal - Basic 4":
I used these Dampers during initial construction of my home, three years ago. I have one fan in the attic that services 4 of the ZRTs all connected to timing swithces. So far, these ZRTs have performed flawless. What I like is that there is zero fan noise (only the sound of air flowing). I do not know how hard they would be to install post construction, but as initial build, they are as easy to install as a rough-in "can" light assembly. The only tricky part could be the wiring. If wiring doesn't make sense to you, let an electrician do it. If you "get" circuits, this is easy. Duct running is easy. Hope this helps someone!
